Greek police have used water cannon and tear gas to quell violent protests, as politicians voted to impose fresh austerity cuts.

Around 100,000 protesters marched to the main square outside the parliament building in Athens to protest the £10.7bn cuts and reforms essential to unlock further monetary aid.

The measures are for 2013/14 and include new, deep pension cuts and tax hikes, a two-year increase in the retirement age to 67, and laws that will make it easier to fire and transfer civil servants who are currently guaranteed jobs for life.

The violence broke out after protesters tried to break through a barricade to enter the parliament building.

TV footage showed smoke and small fires around the building as protesters threw petrol bombs and police responded with stun grenades.
